Are minimum wages to blame for informality in the labour market?

The paper estimates the impact of the minimum wage on formal and informal employment in a developing country combining the use of aggregate time series data with modern time-series methods. The analysis is carried out for the case of Brazil over the period 1982-2002. The hypothesis under investigation is that minimum wage rises price workers out of the formal labour market and into the informal sector. The modelling strategy involves the estimation of the long-run structure as well as the short-term dynamics of employment equations in which the minimum wage enters as an explanatory variable. © 2004 Kluwer Academic Publishers.
